MALT-BRUSHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 417,631, dated December1'7, 1889.

Application filed March 7, 1889.

To all whom it may concern.-

Be it known that I, JOHN M. CASE, a citizen of the United States,residing at Columbus, in the county of Franklin and State of Ohio, haveinvented certain new and useful Improvements in Malt-Brushing Machines,of which the following'is a full, clear, and exact specification,reference being had to the accompanying drawings, in whichc Figure I isa side elevation of my machine, and Fig. II is a longitudinal section ofthe same. v

This machine has for its object to aiford simple, compact, and efficientmeans whereby the roots or germs maybe removed from malt or from thebarley after it has been germi nated or rotted and dried.

To this end the machine consists in mounting in a suitable frame ahopper, a feed-box beneath said hopper, a concave perforated cloth intowhich said feed-box delivers, a rotary brush-cylinder mounted above saidconcave cloth in such close proximity thereto as to act upon a layer ofmaterial collected therein, a suitable spout leading from the edge ofsaid cloth opposite to the feed-box, and a vertical suction chamber orspout, with the upper end of which communicates an airtrunk and thelower end of which communicates a conveyer-trough, a suction-fan beingalso connected with the air-trunk, and suitable air-inlets being formedat the desired points in the vertical suction-spout.

My machine further consists in certain details of construction of theabove-named principal parts, all of which will be more fully hereinafterdescribed, and particularly pointed out in the claim.

In the above-mentioned drawings, 1 represents the hopper, carried by andcommunicating with a feed-box 2. In this feed-box is located beneath themouth of the hopper a sh elf 3, which catches the material and allows itto gradually flow over a low vertical side 29. This feed-box is furtherprovided with an inclined bottom 7, extending through an opening 8 intothe brush-chamber 12 of the machine. The outlet of the feed-box is overthis inclined bottom.

11 represents the axis of the rotary brush- Serial No; 302,252. (Nomodel.)

cylinder 15,having suitable brushes 16, which brushes are preferablymade of rice-root or other coarse material. The shaft 11 also carries atone end the eccentric 10 and connecting-rod 9, the other end of which isbolted or otherwise secured to the side of the feed-box 2. The feed-box2 is hung by means of rods 4, pivotally connected at 5 to the frame 30,and similarly connected by means of wristpins 6 to said box. From thisconstruction it will be observed that upon rotation of the cylindricalbrush a reciprocating motion will be imparted to the feed-box 2, whichwill cause the material to be treated to gradually flow in a thin streamfrom the shelf 3 over the incline 7 and into the chamber 12.

14 is the concave cloth, secured in any preferred manner in thebrush-chamber. This concave cloth is perforated, and preferablyconstructed of rolled wire, the mesh being of such size as to permit thepassage of a large proportion of the roots or germs, which are collectedby a hopper and conveyor 13 below, but not to permit the passage ofcoarse material.

17 represents the outlet from the concave cloth to the suction-spout,which is formed by the angle-boards 18 19, so constructed as to allowthe material to freelypass off at the bottom and catch any materialwhich may be thrown too far upward by the bruslrcylinder at the top andthen guide the material downward as it enters the suction-spout 20.

21 22 are inlets in this suction-spout, which may be locatedat anydesired points beneath the opening 17.

23 is an air-passage communicating between the air-trunk 2 1 andsuction-spout 20. The air-trunk 2i is provided with a regulatorvalve ordamper 2 7, and communicates through eye 25 with the fan 26. The fan 26has the outlet 28, which may communicate, if desired, with any suitabledust-collector or other mechanism in which it may be desired to collectand treat the roots or germs of the barley.

I have only shown a longitudinal section of my machine, inasmuch as theparts are all clearly shown thereby, and I desire it understood that thefeed-box, concave cloth, rotary of the machine.

brush, suction-spout, air-passage 23, and airt-runk all extend to nearlythe whole length The fan 26 has a suitable driving-shaft, and the wholemachine is supported by a suitable frame 30, constructed in anydesirable and convenient form.

This machine is intended to be constructed so as to occupy small space,but to treat the material very eitectively. The material is fed in abroad but thin stream onto the concave cloth, where it is thoroughlybrushed and scraped to remove allthe roots, some of which pass down intothe hopper, the remainder passing off with the coarse material and beingdelivered in a very thin stream into the suction-spout, where the upwardcurrent is strong enough to completely remove all the remaining roots orgerms and carry them over into the fan. The suction-fan, as beforestated, is

connected to some suitable dust-room or dustcatcher, or it may be adust-catching fan so arranged as to both produce the suction and catchthe dust.

If desired, means may be provided whereby the cloth and brush may bebrought closer together or farther apart, so as to regulate the actionof the brush upon the material. This could be done by raising orlowering one end of the cloth or by raising or lowering the jour-' nalsof the cylinder.

Having thus described my invention, the following is what I claim as newtherein and desire to secure by Letters Patent:

In a machine for removing the germs from malt, the combination of anoscillating longitudinal feed-box having a broad deliveryspout 7, astationary perforated concave cloth, onto which the feed-box empties, arotary brushing-cylinder above the cloth acting upon the material, alongitudinal angular guidespout or passage 17, for catching the materialwhen thrown up by the brush and directing it downward, and a narrowvertical suctionspout, into which the spout 17 empties, having asuitable fan, and the openings for inletof air just below the spout 17,all substantially in the manner and for the purposes explained.
